The difference in concentration of a substance across space is called a?
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
Term for the movement of substance against a concentration gradient?
active transport eduction. this is the process in which this moves across. peanut butter jelly time
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
What term describes the different in the concentrations of a substance across a cell's membrane?
concentration gradient
What processes could result in the net movement of a substance into a cell if the substance is more concentrated in the cell than in the surroundings?
Active transport or facilitated diffusion could result in the net movement of a substance into a cell if it is more concentrated inside the cell than in the surroundings. In active transport, energy is required to move the substance against its concentration gradient. In facilitated diffusion, specific carrier proteins help the substance move into the cell down its concentration gradient.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Is the movement of a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What is the movement a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
The difference in concentration of a substance across space is called a?
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
Is diffusion an active mechanism?
False
When a substance moves from an area of low concentration to an area of high concentration the substance moves its concentration gradient?
When a substance moves from an area of low concentration to an area of high concentration, it is moving against its concentration gradient. This process typically requires energy, as it is not a passive movement. Such transport mechanisms include active transport, where cellular energy (like ATP) is used to facilitate the movement. In contrast, substances usually move from high to low concentration naturally, which is known as moving down the concentration gradient.
Term for the movement of substance against a concentration gradient?
active transport eduction. this is the process in which this moves across. peanut butter jelly time
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
What is the movement of a substance against the substances concentration gradient?
Active transport, or reverse osmosis; depending upon conditions.
Movement of a substance down the substance's concentration gradient?
diffusion
How long does movement occur across a concentration gradient?
Movement across a concentration gradient occurs until equilibrium is reached, where the concentration of a substance is the same on both sides of the gradient. The rate of movement depends on factors such as the size of the gradient, temperature, and properties of the substance.
